My Inbox Keeps Getting Spam Emails; What To Do?
Unfortunately, there is little one can do to prevent spammers from filling your inbox with junk mail. However, you can install anti-spam applications on your respective mail servers. Anti-spam techniques generally employ one or more methods to detect spam and prevent their entry into your inbox.
The first step is to know what a spam filter is and how it works. After this, you can choose from a wide variety of email spam filters and decide the best email spam filter for your inbox. For outbound spam filtering, small and medium businesses who handle a lesser volume of emails can go for a free email spam filter.

How To Avoid Landing In The Receiver’s Spam Folder?
Another crucial aspect of outgoing emails is how to avoid spam filters of the recipient. For this, one has to make sure the email design doesn’t contain specific attributes through which the recipient’s spam service marks it as spam. It is essential to remember that it is almost impossible to draft a message that can escape a series of filtering techniques. Hence, here’s what you can try: Use various kinds of overlapping filtering methods simultaneously. However, ensure that the email server is not bombarded by several filtering methods at once, or you will observe a visible effect on your server.
As exasperating as email spam can be, the solution to it is relatively simple and convenient. Today’s ever-growing market is in a continuous process of developing anti-spam technologies. These spam filtering techniques ensure that the inbox is safeguarded against malicious content and provide the delivery of emails in the receiver’s inbox, not the spam folder!
